The graph helps right off : https://www.desmos.com/calculator/rlynsff8rp
x^2 - 3x x ( x - 3) 1x
f(x) = ___________ = ___________ = _____ (1)
2x^2 - 3x - 9 (2x + 3) (x -3) 2x + 3
The "hole" occurs where x - 3 = 0 → x = 3
To find the y coordinate of the "hole" we have 3 3 1
_______ = ___ = __
2(3) + 3 9 3
So....the "hole" is at (3, 1/3)
The graph shows that the x intercepts and the y intercepts are the same ....i.e., at 0
The horizontal asymptote is just the ratio of the coefficients on "x" in (1)
So.....this is y = 1/2
The vertical asymptote is where 2x + 3 = 0
So
2x + 3 = 0
2x = -3
x = -3/2
